Ed Maste ae500c1ff8 Update to ELF Tool Chain r3668
Highlights:
- Make sure that only TLS sections are sorted into TLS segment.
- Fixed multiple errors in "Section to Segment mapping".
- Man page updates
- ar improvements
- elfcopy: avoid filter_reloc uninitialized variable for rela
- elfcopy: avoid stripping relocations from static binaries
- readelf: avoid printing directory in front of absolute path
- readelf: add NT_FREEBSD_FEATURE_CTL FreeBSD note type
- test improvements

NOTES:

Some of these changes originated in FreeBSD and simply reduce diffs
between contrib and vendor.

ELF Tool Chain ar is not (currently) used in FreeBSD, and there are
improvements in both FreeBSD and ELF Tool Chain ar that are not in
the other.

.Dt ELFTC_SET_TIMESTAMPS 3
.Os
.Sh NAME
.Nm elftc_set_timestamps
.Nd set file timestamps
.Sh LIBRARY
.Lb libelftc
.Sh SYNOPSIS
.In libelftc.h
.Ft int
.Fn elftc_set_timestamps "const char *filename" "struct stat *sb"
.Sh DESCRIPTION
The
.Fn elftc_set_timestamps
function is used to set the access and modified time stamps on a file
based on the contents of a
.Vt "struct stat"
descriptor.
.Pp
Argument
.Ar filename
names an existing file in the file system.
.Pp
Argument
.Ar sb
points to structure of type
.Vt "struct stat"
populated by a prior call to
.Xr fstat 2
or
.Xr stat 2 .
.Sh IMPLEMENTATION NOTES
This function will invoke the high-resolution
.Xr utimes 2
system call if the underlying operating system supports it.
On operating systems lacking support for
.Xr utimes 2 ,
the function will use lower resolution
.Xr utime 2
system call.
.Sh EXAMPLES
To set the access and modified times for a new file to those of an
existing file, use:
.Bd -literal -offset indent
struct stat sb;
const char *existing_filename, *new_filename;
if (stat(existing_filename, &sb) < 0)
err(EXIT_FAILURE, "stat failed");
if (elftc_set_timestamps(new_filename, &sb) < 0)
err(EXIT_FAILURE, "timestamps could not be set");
